The new ERGON range of automatic packers is based on design choices inspired by key concepts such as ergonomics, technology, sturdiness and modularity, masterfully blended to mark a new, significant evolution in the history of SMI products.
You can point out the new ERGON packers rather quickly due to the rounded profile of the movable safety guards, which allow to house all the motors on the outside with respect to the mechanical units they run, facilitating line operator access when performing maintenance.
The CWP ERGON series includes automatic machines for the packaging of plastic, metal , cardboard and glass containers in corrugated cardboard cases and/or trays without film. The octagonal or rectangular trays can have walls of either the same height or different heights.
The CWP ERGON series case packers can achieve an output up to 40 packs per minute, according to the product.
The pack collations can vary according to the containers shape and dimensions; in general, the most requested collations are: 2x3, 3x4 and 4x6.
CWP case packers are equipped with an electronic product-grouping system and manual format changeover.
1On the machine's inlet conveyor belt, featuring low-friction chains made of thermoplastic material, a specific group of motorized oscillanting guides accurately lines up the loose containers moving towards the pack formation zone, where the containers are clustered in the selected format through electronically synchronized fingers, operating in continuous motion.
2A corrugated cardboard blank is picked from the blanks magazine by an alternate motion cardboard blank picker composed of a group of suction cups, moves along the blank climb and places itself underneath the group of products in transit with the short side leading. In the tray/case former, the cardboard blank is folded and wrapped around the products by special guides.
3The flap folding devices fold the blank’s side flaps and then the upper/lower flaps of both the front and back side of the pack. The hot melt glue sealing ensures an excellent resistance of the pack.
4At the machine outlet, the pack walls are pressed by special guides that guarantees a perfect and lasting squaring of the cases. Such system ensures perfect and durable pack squaring, if compared to pressing systems with rotating chains, which cannot provide the same quality standard.
Machine bearing frame made of sand-blasted and powder-painted steel
The machine is equipped with sliding protection doors in anodised aluminium featuring a rounded shape which let all the motors (featuring low energy consumption) be placed externally if compared to the mechanical groups they activate.
The closing system of doors is equipped with a slow-down device, which accompanies the door smoothly in its final phase of closure
Absence of gearboxes and prevailing employment of ICOS brushless motors equipped with digital servo-driver integrated into the motor
Continuous motion product grouping device, with electronically synchronized fingers made of plastic material
For life lubricated pads
Infeed conveyor with chains made of thermoplastic material featuring low friction coefficient and a motorized system of oscillanting laning guides
Cardboard magazine situated beneath the infeed conveyor, adjustable according to the blank size
Alternate motion cardboard blank picker, equipped with suckers
POSYC® control panel mounted man-high and running the whole length of the machine (fixed on AFW/LSK/LWP models)
Compact size and competitive prices
Thanks to their reduced size, the ERGON machines are the ideal solution for the customers who do not possess large plants. Moreover, the price of the ERGON models is very competitive, despite the high-tech solutions and the use of very reliable components. All ERGON models can be customized, in order to increase their basic functions.
SMI machines are designed according to advanced principles of module assembly and feature interchangeable mechanical and electronic components, which ensure a reduction of the down-times during technical interventions or programmed maintenance and the optimization of the use of spare parts on stock.
SMI machines can package a wide range of products in several pack collations, so as to effectively meet the end user's current and future requirements.
Moreover, each machine can be equipped with additional devices, which increase its basic functions and ensure a high level of customization of the final package.
Motors directly connected to the drive shafts
SMI machines do not include gearboxes: the motors are directly connected to the drive shafts. The consequent advantage is the reduction of maintenance, energy consumption and noise.
Continuous motion pack formation
The continuous motion packaging system ensures a fluid production process and protects the containers from strokes, thus granting more reliability, a better quality of the pack and a reduction of mechanical wear.
Thermoplastic material dividing pins
In the pack formation zone, the use of dividing pins made of thermoplastic material, which last longer than those made of metal, reduces the machine noise and protects the fragile containers (such as glass containers) and their labels.
Easy and low-cost maintenance
The rounded protection doors of ERGON models allow broader space inside the machine and thus the motors can be mounted externally on the machine side edges.
Therefore, they are easily accessible and reachable for maintenance.
Actually, the operator doesn't need to enter the internal parts of the shrink wrapper when carrying out
All of the models of SMI case packers can realize hexagonal or octagonal microflute/miniflute cardboard cases, which can be subject to more sophisticated printing processes, as compared to the standard corrugated cardboard.
SMI case packers are equipped with fixed guides, which press the pack walls at the machine outlet. This system ensures a perfectly balanced, resistant case, whereas the rotary chain pressing systems can not guarantee the same quality level.
"User-friendly" man-machine interface
The POSYC® control panel, sliding on a boom running the whole length the machine, is very easy to use, thanks to the intuitive interface, the touch screen and the diagnosis functions and real-time technical support on the POSYC®.
The PID SBP® inserts stretched board pre-assembled partitions into cardboard boxes, in order to protect fragile products (such as glass containers) and save their labels from abrasions.
This device can be installed on the WP wrap-around case packers and on the CM and LCM 40 combined packers.
Compared with the traditional inserting systems of non-preassembled partitions, the PID SBP® allows to:
reduce the partitions purchasing cost by about 20% and their storage volume by at least 60%;
have a more compact machine, since both the partition magazine and the Partition Inserting Device are mounted on top of the machine; in this way, the machine dimensions are the same as those of a conventional case packer;
speed up the partition insertion operation and the loading times of the relevant magazine, since partitions are already pre-assembled;
reduce the sensitivity of partitions to humidity and climate changes.
The PID SBP® and the pre-assembled partitions magazine are mounted at the machine inlet, on top of the pack-forming section. The maximum operating speed is 40 packs/minute (1-head model) or 60 packs/minute (2-head model).
A mechanical arm equipped with vacuum suckers picks a stretched board pre-assembled partition from the partition magazine, opens it and lowers it between the products that have just been grouped in the required pack collation.
Finally a cardboard blank is wrapped around the products by means of special guides, thus forming a case.
